Abstract
Description
- This invention relates to guide wires for use with catheters and more particularly, to guide wires with an attenuated diameter and having torsional control.
- Guide wires heretofore have been provided, however, guide wires which make it possible to penetrate small blood vessels with adequate proximal strength for catheter tracking capabilities as, for example, in the kidney and which still permit high torsional capabilities have not been available.
- There is therefore a need for a torsional attenuating diameter guide wire.
- It would be desirable to provide a guide wire which has a progressively attenuated diameter and to provide a guide wire of the above character which has high torsional capabilities.
- It would further be desirable to provide a guide wire of the above character which is provided with a small tip facilitating deep penetration into small vessels and to provide a guide wire of the above character which has a relatively large proximal diameter to facilitate tracking of the catheter while it is in use.
- The present invention is further described by way of example only with reference to the accompanying drawings, in which:
- Figure 1 is a side elevational view of a torsional guide wire with a progressively attenuated diameter incorporating the present invention.
- Figure 2 is an enlarged view of the distal extremity of the guide wire shown in Figure 1.

- Figure 8 is a cross sectional view of the proximal coil utilized in the guide wire shown in Figure 1.
- Figure 9 is a side elevational view of the plastic tubing utilized in the guide wire shown in Figure 1.
- In general, the torsional guide wire with a progressively attenuated diameter is comprised of an elongate core element having proximal and distal ends and having a decreasing cross sectional area in a direction towards the distal end. It is also comprised of a coil carried by and secured to the core element and extends over the distal extremity of the core element. The coil has proximal and distal ends and has a diameter which decreases in a direction towards the distal end. The coil is formed of wire which has a diameter which decreases from one end to the other end and is wound in a helix so that the larger diameter wire begins in a region closer to the proximal end and the smaller diameter wire ends in a region closer to the distal end.
- More in particular as shown in Figures 1 and 2 of the drawings, the attenuating diameter guide wire 11 consists of a
core element 12. Thecore element 12 is shown in detail in Figure 3 and is formed of a suitable material such as stainless steel and has a suitable diameter such as from .015 to .025 inch and preferably a diameter of .020 inch, plus or minus .0003 inch and having a suitable length such as 7 feet. The core element is provided with proximal anddistal ends core element 12 is centerless ground to provide a core wire which has a decreasing cross sectional area in a direction towards the distal end. Thus as shown, thecore element 12 is provided with a cylindrical portion 12a which extends over a major portion of the length of the core element. Atapered portion 12b adjoins the portion 12a and extends over a suitable distance such as 2 1/2 centimeters and provides a taper, for example, from .020 inches to .0145 to .0155 inches and preferably a dimension of .015 inches. The remaining length of the core element is centerless ground to a dimension such as .015 inches for a length of approximately 35 centimeters. Thereafter, in a further grinding operation a transition region 12d is provided which over a length of approximately 2.5 centimeters provides a transition from .015 to .009 to .010 inches. The followingportion 12e of approximately 10 centimeters is centerless ground to the .010 inch dimension. Thereafter an additionaltransitional region 12f is provided which provides a transition from .010 inches to .002 to .0025 inches. This transition extends over approximately 3 centimeters. The remaining distal extremity of the core wire as, for example, a length of approximately 2 centimeters is ground so that it has a diameter of .002 to .0025 inches. Thus it can be seen that a core element has been provided which has been carefully dimensioned by centerless grinding to provide a decreasing cross sectional area or a taper as hereinbefore described. - The guide wire 11 also consists of a
tapered coil 16. Thecoil 16 itself is shown in Figure 6. The wire 17 from which it is wound is shown in Figure 4. Themandrel 18 on which the wire 17 is wound to form thecoil 16 is shown in Figure 5. The wire 17 is formed of a suitable material such as stainless steel and has a length of approximately 7 feet and a diameter of .007 inches plus or minus .0002 inches. A major portion of the wire 17 has an outer dimension of .007 but the remainder of the wire is centerless ground to provide a decreasing diameter towards the distal extremity of the wire. Thus in addition to the cylindrical portion 17a there is provided atransition portion 17b of a suitable length such as 2.5 centimeters in which there is a dimension change from .007 inches to .005 inches for a length of approximately 60 centimeters from the distal extremity of the wire. Aportion 17c of the wire has a diameter of .005 inches. At another portion, 17d of the wire, another transition in diameter is made over a distance of approximately 2.5 centimeters from .005 inches to .003 inches. There is then provided aportion 17e having a length of approximately 10 centimeters which has a diameter of .003 inches. - The
mandrel 18 on which the wire 17 is wound is shown in Figure 5 and is formed of a suitable material such as steel having a diameter of .019 inches extending over the portion 18a. Atransition portion 18b is provided extending over 2 1/2 centimeters in which the diameter is decreased from .019 to .015 inches. Anotherportion 18c is provided having a diameter of .015 inches extending up to another transition portion 18d in which the diameter is decreased to .011 inches so that the distal extremity of the mandrel provided by theportion 18e has a diameter of .011 inches and a length of approximately 12.5 centimeters. - The coil or
coil section 16 is then formed by taking the wire 17 and taking the end of the smallest diameter and starting it on the mandrel at thepoint 21 and progressively winding the wire onto themandrel 18 in a helix in a direction towards the larger diameter end over a distance of approximately 15.5 centimeters. Thus, the larger diameter wire begins in a region closer to the proximal end and the smaller diameter wire ends in a region closer to the distal end of thecoil 16. After the winding has been completed, the core orcoil section 16 can be removed from the mandrel and trimmed to length. The proximal and distal ends of thecoil 16 can be stretched apart slightly so that the ends can be screwed together with other coils or coil sections as hereinafter described. - The
coil section 23 which forms the tip of the guide wire 11 is formed of a suitable wire such as a platinum alloy having a diameter of .003 inches plus or minus .0002 inches. This wire 11 is 3 centimeters plus or minus one millimeter and having an outside diameter of approximately .018 inches maximum. The interior diameter corresponds to the diameter of the mandrel which is approximately .011 inches. One end of thecoil 23 is stretched so as it make it possible to screw into another coil end as hereinafter described. - The coil or
coil section 16 after being wound or removed from the mandrel is formed so that it is provided with a portion 16a having an outside diameter of approximately .035 inches, anotherportion 16b having an outside diameter of approximately .027 inches and adistal extremity 16c having an outside diameter of approximately .018 inches. - Another core or
coil section 26 is provided which can be identified as the proximal coil. This coil is formed by winding a suitable material such as stainless steel wire having a diameter of .00.7 inches on the portion 18a of themandrel 18 having a diameter of .019 inches. Thecoil 26 is then coated with a suitable plastic material such as Teflon and is cut to a suitable length, as for example, 81.5 centimeters with one centimeter of the same near the distal extremity being uncoated and stretched for a screw together brazed joint as hereinafter described. - The guide wire 11 also includes a length of
shrink tubing 31 having a suitable length as, for example, 45 centimeters as shown in Figure 9 and having an outside diameter of approximately .41 inches and an inside diameter of approximately .026 inches. - With these fabricated components hereinbefore described, the guide wire may now be assembled. To start the assembly, the
shrink tubing 31 is taken and is shrunk down onto theground core element 12 approximately 100 centimeters from the distal tip of thecore element 12. This can be accomplished in any suitable manner as, for example, by a batch process or by individual treatment of the shrink tubing with heat. The Teflon coatedcoil 26 is then placed on thecore element 12 and bonded to thecore element 12 at the point at which it is juxtaposed to the distal extremity of theshrink tubing 31 by the use of a suitable material such as Cyanoacrylate. The coil orcoil section 16 is then positioned on thecore element 12 and its proximal extremity is threaded into the distal extremity of the Teflon coatedcoil 26 and thereafter abrazed joint 33 is formed to bond the juxtaposed ends of thecoil 16 to thecoil 26. The screw together.joint 33 with the brazing is shown in Figure 2. Agold alloy 33 can be utilized to form the joint 33. The use of gold which is radiopaque permits the doctor to see where the .035 portion of the guide wire 11 starts by the use of a fluoroscope. Thecoil 16 when so positioned on thecore element 12 has its larger diameter wire beginning in a region closer to the proximal end and its smaller diameter wire ending in a region closer to the distal end. - The
platinum coil 23 is then taken and its proximal extremity is positioned on thecore element 12 and threaded into the distal extremity of the coil orcoil section 16. After they have been screwed together, a suitable solder can be utilized for forming a joint 34 between the juxtaposed ends of thecoils core element 12. Atip 36 which has a rounded configuration is then provided on the distal extremity of theplatinum coil 23. - After these assembly operations been completed, a
torquer 38 of a conventional construction is mounted on the proximal extremity of the polyethylene shrinktubing 31. Thetorquer 38 firmly grasps the guide wire 11 and makes it possible for a physician by use of a hand to apply torque to the guide wire. The guide wire can have a suitable overall length as, for example, a length of 145 centimeters. - The operation and use of the guide wire 11 is very similar to that for other guide wires. It, however, has numerous characteristics which are particularly adapted to particular types of operations as, for example, where it is desired to make deeper penetration into the kidney of the human body. It also has a very small diameter tip while still having a relatively large diameter proximal to the tip to facilitate tracking of the catheter under the fluoroscope. The tapering of the coils or coil sections is particularly important and is made possible by the use of a tapered wire which is utilized for forming the tapered coil or coil sections. In addition, the screw together joints between the coil sections provides for transitions between the coil sections while still providing a smooth exterior circumferential surface.
- It is apparent from the foregoing that there has been provided a new and improved guide wire which has a progressively attenuated diameter and which has good torsional capabilities. It also has a construction which can be economically manufactured in quantity with great precision. Even though a tapered tip sub assembly has been provided in connection with a Teflon coated coil and polyethylene shrink tubing, there is a very smooth transition provided between the different materials utilized in the guide wire facilitating its use in connection with small vessels in humans.
